Supplementary description. The tip of the male paraproct is excised, the rounded medial lobe is longer than the inner. The cercus has a single outer tooth. In caudal view of the cerci the strongly sclerotized dark cap has a straight edge in very oblique position, the inner and outer teeth are very unequal. The soft medial end portion is large. It is increasingly pigmented and sclerotized towards the down-hanging medio-ventral apex which forms a blunt point (Fig. 19).

The epiproct contour is almost rhomboid (Figs. 17, 18). The looped sclerite joins the median toothbearing sclerite at an oblique angle. The apical sclerite is slender and semi-erect. The tip may turn slightly mediad, its surface is covered with delicate wrinkles. Along the outer edge there are two or three very short and stout spines.

Notes. N. jilinensis was described after a single male taken in China, near the northern border of the Korean peninsula. It is new for Korea.
